A eonr'onn'rion 0E NEW YORK i HAIR-CURLING DEVICE Application filed March 26,

My inventionrelates to a new and improved hair curling device. Y h One of the objects of my invention 1s to provide an improved hair curling device by means of which the temperature to which the hair is subjected during the curling 0perat-ion may be readily and eiliciently regulated.

Another object of my invention is toV provide a device of this type in which the temperature to which the hair is subjected is regulated by regulating the escape of heated air from the device.

Another object of my invention is to provide a device of this type whichshall be efficient and durable and which can be simply and cheaply manufactured and assembled. v

Other objects of my invention will be set forth in the following description and drawings which illustrate a preferred embodiment thereof, it being understood that the above general statement of the objects of my invention is intended to generally eX- plain the same and not to limit it in any manner.

Fig'. 1 is axfront elevation showing the improvedl device.

Fig. 2 is a vertical central section partially in elevation.

Fig. 3 is a sectional view on the line 3-3 of Fig. 2, the vertical ports being shown in the closed position.

Fig. d is a view similar to Fig. 3, the said ports being shown in the open position.

Fig. 5 is an elevation of the device with the inner tube removed.

Fig. 6 is a side elevation showing the inner tube of the device.

Fig. 7 isa top view of Fig. 5, certain of the parts being broken away lto illustrate certain details. l

Fig. 8'is a top view of Fig. 6.

The bottom portion of the `device comprises an annular member 1 made of any suitable metal and having an open bottom. This annular member 1 is provided with a cylindrical insert 7, which is connected by a drive fit or byl any other suitable meansto a cap 6, Whiehis connectedto thebottom an- 1928. ScI'ial; No. 264,594.`

nular member 1-`by means of adrive fit or other suitable means. The member 1 and the insert 7 constitute an annularH end member. As shown in Fig. 1, the inner endl of the inner tube 9, which is more fully described later herein, abuts a lateral wall of said combination end member so as to p rovidea` bearingv for the turningA movementof the inner tube. Likewise, the detents 27, which are also later more fullyl described, retain the inner tube withinsaid outer tube while permitting the turning of thev inner tube with respect to said outer tube. The insert 7 and the cap Gare also preferably made of any suitable metal. The interior of the annular bottom element 1 is suitably heated, as for example, by a suitable resistance coil or coils. rlhese resistancev coil`or coils are not shown as-such a heating device is in itself old and well known, it being suflicient to state that these coils arey insulated froin themembers `1 and 7 and that suitable i-nsulationis provided to throw` the heat inwardly,that is, towards the interior of the cylindrical insert 7. The supply wires W forfthe said heating element preferably pass through hollow tubes 2, three of which are provided as `shown in Figs. 3 and 4, for` example. Two of these wires WV are respectively connected to the terminals of a source of electric power and one of said wires is grounded so that the electric resistance coil or coils are .suitably ,0 r-ounded.` The tubes' 2 are suitably connected tothe cap 8 as by' means' of a drivel iit or any other suitable means and their upper'ends are preferably molded integral with the cap 17 made of Abakelite or other suitable insulating` material. i, The outer metal. tube 8 is provided with a flange at the bottom thereof which isconnected to the cap 6 by means Lof a drive t or any other suitable means. The upper end of the outer tube 8 can be molded integral with the insulatingcap'l? or else thecap 17 and the. topf'flange of the outer tube'8 may be connected by screws 18. The topy portion of the cap 17 is hollow and it is provided with a horizontal insert 30,

`which may be made of any suitable metal or other material molded into position. n Three iii) Sii

detents 27 are slidably located within the chamber thus formed in the upper part of the cap 17, and said detents 27 are inwardly pressed by means of compression springs 36 so that they normally occupy the position shown in Fig. 2. As clearly shown in Fig. 5 for example, the outer tube 8 is provided with a plurality of vertical ports 10. The inner tube 9 which is shown in Fig. 6 is provided with an offset intermediate portion, having a series of inner ports 11 which correspond in number, size and location to the outer ports 10 of the outer tube' 8. The inner tube 9 is provided with a lower bead 14, an upper bead 15 and with a knurled head 26 also made of bakelite or other suitable insulating material. The inner tube 9 is held in position by means of the three detents 27 which engage the same above the bead 14. These detents 27 permit the turning of the inner tube 9. The top bead 15 also acts as a bearing to permit the free turning of the inner tube 9 within the outer tube 8.

As clearly shown in Fig. 2, the cap 26 of the inner tube is hollow. As shown in Fig. 8, upper and lower shutters 21 are provided. The top shutter 21 is firmly held against movement in the top bead 15, by means of a drive fit or other suitable means. 'Ihe lower shutter 21 is connected to a revoluble head 2O made of balelite or other suitable insulating material. The respective shutters 21 are provided with horizontal ports 22 which are alike in size, shape and location. l

When the parts are assembled as shown in Fig. 2, a relatively narrow tube upon which the curl of hair is suitably wound and mounted in the well known manner, is passed through the bottom of the apparatus into the interior thereof so thatthe lock of hair does not touch any of the parts, but is heated by the resistance element or the like. If the inner tube is in the position shown in Fig. 3, then the vertical ports are closed and if the horizontal ports 22 are also closed, little or no air can escape from the apparatus and the lock of hair is subjected to a relatively high temperature. However, by opening either the vertical ports or the horizontal ports to any desired extent, the escape of air from the apparatus can be regulated so that the temperature to which the lock of hair is subjected can be accurately regulated. While I have specified the device as being held in the vertical position, this description is only for the purposes of convenience and it is obvious that the operation of the device does not depend upon the position in which it is held.

l I have shown a preferred embodiment of my invention, but it is clear that numerous changes and omissions could be made without departing from its spirit.

I claim 1. A hollow hair curling device adapted to be heated and adapted to impart the heat thereof to a lock of hair located in the interior thereof, and a plurality of adjustable means adapted to regulatetheescapeofheatfrom the interior of the said device, one of said adjustable means being adapted to control the escape of heat in an axial direction, the other of said adjustable means being adapted to control the escape of heat in a direction lateral to said axial direction.

2. In a hair curling device, the combination of a hollow member adapted to be heated, an outer tube connected to said hollow memben and having acap, spring actuated detent means located in the said cap, an inner tube revolubly mounted within the said outer tube, said inner tube having a bead above which the said detent means are adapted to engage, the said tubes having` port means whose opening is adapted to be regulated by the turning of the saidinner tube.

3. For use in a hair curling device, an inner tube having adjustable shutter means located at the top thereof to regulate the escape of air therefrom, said shutter means being movable in a direction lateral to the axis of the device.

4. A hollow hair curling device adapted to be heated and to impart heat to a lock of hair located in the interior thereof, and adjustable means adapted to permit and to regulate the escape of air from the side of the said device, and additional adjustable shutter means movable in a direction lateral to the axis of the device.

5. A hollow hair curling device comprising an outer tube provided with port means in the wall thereof, an inner tube having cooperating port means,` said inner tube projecting from said outer tube so that the inner tube can be conveniently manipulated, and bearing means intermediate said tubes and adapted to permit the inner tube to be turned with respect to the outer tube, said outer tube having inwardly directed and spring actuated detent means to prevent any relative axial movement of said tubes.
